本發明的目的是在於解決前述問題點，並提供具有含有彈力感的緩衝性，即使返覆或長時間使用也不容易損害彈力感，且緩衝性的耐久性佳的立體編物。本發明的更具體的目的：特別是，使用在吊床式座墊的情況時，顯示具有反彈感的緩衝性，並且，對人體的貼身感良好，且坐後不會回復至原來的形狀，也就是彈性復原少形態保持性佳的立體編物。本發明的進一步的目的爲提供高頻率的振動減衰性佳的立體編物。〔發明的揭示〕本發明，是針對由組合連結立體編物的表背的針織物的單絲的直徑及彎曲形狀、立體編物的壓縮特性、壓縮撓屈特性及纖維素材所構成的立體編物的構造，經反覆硏究，始獲得本發明。經濟部智慧財產局員工消費合作社印製也就是說，本發明的體編物5針對由表背二層的針織物、及連結該二層的針織物的單絲的連結線所構成的立體編物，其特徵爲：立體編物中的單絲的曲率爲〇 . 〇 1 〜1 · 6 ，立體編物的5 0 %壓縮時的單絲的彎曲伸長率爲2 0 %以下。〔實施例〕茲佐以圖面說明本發明之座墊用立體編物。由圓型針織機編機、雙圓針織機、橫針織機編成立體本紙張尺度適用中國國家標準（CNS ) A4規格（210 X 297公釐） 565638 經濟部智慧財產局員工消費合作杜印製 A7 B7五、發明説明（3) 編物的情況時，連結表背的針織物的連結線，必定在朝某一方向彎曲的狀態下編入。因此，在立體編物加上厚度方向的力量的話，已彎曲的連結線會更彎曲，但放開力量的話，會連結線回復至原來的狀態。這時所產生的連結線的彎曲及回復的舉動大大影響立體編物的緩衝性。本發明即是依據此知識。本發明的立體編物，在連結表背二層的針織物的連結線的至少一部分必需使用單絲，且使位在立體編物的表背的針織物之間的單絲的曲率成爲0 · 0 1〜1 · 6地編成立體編物，並後處理加工。在此.，所謂的單絲的曲率，是在立體編物中使單絲呈最大彎曲的部分的單絲的中心線所形成的圓弧的曲率。第1圖是顯示從沿著立體編物1的縱列的切斷面所看的單絲的中心線5的一例。單絲的曲率，最好是0 · 03〜1 · 0，但0 · 05〜0 · 7更佳。單絲的曲率未滿0 . 〇 1的話，當在立體編物1的厚度方向加上負荷的情況時，表面的針織物及背面的針織物會朝立體編物的長度方向（沿著縱列的方向）偏移而容易發生剪斷變形，而成爲回復時的滯延損耗大的無彈力感的緩衝性。且，藉由返覆壓縮使該傾向會更增長。單絲的曲率r i 超過1 · 6的話，雖不容易產生剪斷變形，但也成爲無彈力感的緩衝性。且，本發明的立體編物，將立體編物5 0 %壓縮時的單絲的彎曲伸長率爲2 〇 %以下較佳。1 5 %以下更佳， 1 0 %以下最佳。在此，所謂的單絲的彎曲伸長率，是在本紙張尺度適用中國國家標準（CNS ) A4規格（210X 297公釐1 " (請先閲讀背面之注意事項再填寫本頁} 565638 經濟部智慧財產局員工消費合作社印製 A7 B7五、發明説明（4) 將立體編物5 0 %壓縮的狀態下使單絲呈最大彎曲處的凸側表面的伸長率。第2圖雖是將立體編物1呈5 0 %壓縮的狀態下的沿著編物的縱列的切斷面圖’但顯示單絲呈最大彎曲的凸側表面6的一例。單絲的彎曲伸長率超過2〇 %的話，會成爲壓縮立體編物之後的殘留變形大，且壓縮回復性差的立體編物’並且’返復或長時間壓縮後，無法維持具有彈力感緩衝性。立體編物的單絲的彎曲伸長率，7 5 %壓縮時爲2 0 %以下的話’可以提高壓縮回復性、緩衝性的耐久性而更佳。爲了將立體編物的單絲的曲率、及5 0 %壓縮時的單絲的彎曲伸長率位在前述適當的範圍內，必需最適化：作爲立體編物1的單絲的直徑、立體編物中的單絲的編組織 (連結表背的針織物時的寬方向的擺動寬）、編成時的單絲的供給量、立體編物的後處理加工方向（擴幅率、過給率），並將後處理加工後的單絲作成適當形狀。其中，對於單絲的編組織及立體編物的厚度的關係，藉由將連結線朝針織物的寬方向傾斜地連結表面及背面的針織物，並以適當的擴幅率後處理加工，如第3圖所示的沿著橫列的切斷面圖，使從壓縮前的立體編物1的厚度T Q ( m m )減去表面和背面的地的厚度的連結線長Η 1 ( m m )及第4圖所示的5 0 %壓縮後的連結線長Η 2 ( m m )的關係成爲 H1/H2-0 · 55的原因，是因爲將立體編物1的 5〇％壓縮時的彎曲伸長率作成2 0 %時的情況較佳。這 (請先閲讀背面之注意事項再填寫本頁) 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） 565638 A7 B7 經濟部智慧財產局員工消費合作社印製五、發明説明（5) 時，連結線長Η 1及Η 2，如第3、4圖所示地將立體編物1從沿著橫列的切斷面來看時，是表針織物2及背針織物3之間的連結線4的外表上的長度，是沿著橫列的切斷面攝影並測量後所獲的的長度。將連結線沿著橫列方向傾斜的情況時，與傾斜的連結線相反的傾斜方向也將連結線傾斜，而將連結線作成後述的構架構造或交叉構造較佳。立體編物的曲率爲0 · 0 1〜1 . 6，5 0 %壓縮時的彎曲伸長率爲2 0 %以下的單絲的連結線的比率，必需是立體編物的單位面積中連結表背的針織物的單絲的全條數之中的20%以上，最好是40%以上，60%以上更佳。立體編物的連結線，若全部是單絲會較佳，但依據需要編成時交編單絲以外的纖維也可以。例如：交織復絲假捻絲等的話，可以減低壓縮時單絲彼此發生摩擦所產生的令人不快的聲音。爲了將5 0 %壓縮時的滯延損耗降爲5 0 %以上，使連結線的單絲的彎曲伸長率成爲2 0 %以上地適正化：立體編物的厚度、單絲的直徑、單絲的傾斜狀態等，是很重要。另外，將彎曲回復時的滯延損耗爲〇 · 〇 5 c Ν · c m / y a r η以下的單絲使用在連結線上較佳。〇.〇3〇1^.(：111/：73]：]1以下更佳，而〇.〇1 c N . c m / y a r η以下且接近0最佳。且，單絲的直徑D ( m m )及立體編物的厚度T q ( m m )的關係可滿足

%以下較佳，而應力緩和率爲3 0 %以下更佳。應力緩和率爲4 0 %以下的話，即使人坐在立體編物上一定時間，也可以有良好的瞬間的回復性。本發明的立體編物當作吊床式的座墊使用的情況時，壓縮撓屈量爲1 0 m m以上8 0 m m以上的話，可以獲得與人體的貼身感而可以獲得較佳的坐感。在這所謂的吊床式座墊，是指藉由使立體編物的周圍或至少2邊，在座墊框或椅子的框呈緊張狀態或鬆弛狀態下拉開，而使立體編物呈帆的狀態形成座墊的坐部或背靠部。又’所謂壓縮撓屈量，是將切成四角的立體編物的周圍固定在框上，且對於立體編物的表面在直角方向施加負荷時的立體編物的撓屈量，且決定於立體編物的表背的伸長特性。撓屈量未滿1 0 m m的話，當人坐時的下陷量過少，立體編物的座墊面無法貼身在人體上，而使貼身感較硬。撓屈量超過8 0 m m的話，貼身感雖佳，但坐後會容易發生無法回復原來形狀的彈性復原，而使形態保持性不充分。壓縮撓量最好是1 5 m m以上7 0 m m以下，1 5 m m以上6 0 m m以下更佳。本紙張尺度適用中國國家標準（CNS ) A4規格（210x^7^7 ---------—

%以下的原因，是因爲可以獲得下陷量較多且可以提高對人體的貼身性的吊床式座墊。5 %以上4 5 %以下更佳。又，爲了獲得反彈感較強且坐後的彈性復原少且形態保持性良好的吊床式座墊，立體編物的的縱方向及橫方向的伸長率爲0 . 5%以上2 0%以下較佳。1%以上1 5%以下更佳。經濟部智慧財產局員工消費合作社印製然而，立體編物伸長時的縱方向及橫方向的伸長殘留變形，爲了減少坐在吊床式座墊後的彈性復原，最好是 1 0%以下。7%以下更佳，5%以下最佳。爲了使立體編物的縱方向及橫方向的伸長率及伸長殘留變形在適當的範圍內，立體編物的表背的編組織及後處理加工方法變得很重要。表背的編組織是網目等的多孔組織的話，構成1 網目的組織数（横列数）設爲1 2横列以下較佳，後處理加工方法是取得縦方向及横方向的伸長率的平衡，且將横方向擴幅並熱定形較佳。表背的至少一方的編組織是非多孔的平坦組織或凹凸組織的話，所有橫列可以使用：由針織弧所形成的編組織、或針織弧組織及插入組織的複合組織等。爲了在吊床式座墊獲得下陷量多且貼身性良好的緩衝性，而將立體編物的伸長率增爲較大的話，所有橫列不進行無形成針織弧的插入編，而在至少所有橫列的一半以本紙張尺度適用中國國家標準（CNS

經濟部智慧財產局員工消費合作社印製上的橫列進行形成針織弧的編組織較佳。又，爲了在吊床式座墊顯示具有反彈感的緩衝性，且返覆或長時間坐後的形態保持性良好的特性，而將立體編物的伸長率減爲較少的話，將插入線呈直線狀地插入立體編物的表背的至少一方的針織物的縱方向及/或橫方向較佳。因爲將插入線呈直線狀地插入縱方向及/或橫方向，使立體編物的縱方向及/或橫方向的伸長特性，不會大大地影響表背的針織物的組織的變形或網目形態的變形，而由插入線本身的伸長特性所決定。也就是說，因爲人坐上，而使朝呈吊床式張設的立體編物表面幾乎垂直的外力作用，並使立體編物的表背的針織物伸延時，因不容易產生由組織形態或網目形態的變形所產生的纖維間的偏離，而使返覆或長時間坐後的形態保持性良好。在此，所謂將插入線呈直線狀地插入表背的至少一方的針織物，當縱方向的情況時，是指在由鎖編或經平組織編織等的組織所編成的底線的針織弧及沉降弧之間，以每一橫列2針橫移以下的橫移寬插入的狀態’或是指，在連結於立體編物的長度方向的地糸的沉降弧之間上下地插入的狀態下，橫跨立體編物的全長使插入線呈接近直線的形態下插入的狀態。又，當橫方向的情況時，是指在由編鏈組織或經平組織編織等的組織所編成的底線的針織弧及沉降弧之間，使橫跨立體編物的全寬地將插入線呈接近直線形態插入的狀態。這時，使用於插入線的纖維最好使用聚對苯二甲酸丙二醇酯纖維或聚酯系高彈體纖維等的彈性回復性良好的纖維，若是單絲的話，最好本紙張尺度適用中國國家標準(CNS

減少因單纖維之間的摩擦阻力所產生的伸長回復性的阻害。又，插入線爲了防止與底線的滑動，最好由熱融合或樹脂接點等與底線接合。插入線的插入方法，從縱方向插入的話，可以利用編組織插入，從橫方向插入的話，可以使用設有緯線插入裝置的雙羅素斜紋針織機進行緯線插入。立體編物的表背的編組織，不需要相同，雖可以是不同的編組織、不同的伸長特性，但背側的針織物的伸長率比表側的針織物的伸長率少的話，可以更增加人坐時的由單絲所產生的彈力感，且對人體的貼身性良好。將插入線朝縱方向及/又橫方向呈直線狀插入的情況時，也是插入立體編物的背側的針織物較佳。經濟部智慧財產局員工消費合作社印製而且，立體編物的壓縮撓屈時的滯延損耗爲6 5 %以下的話，當使用作吊床式座墊的情況時，因具有反彈感的緩衝性，而較佳。6 0 %以下更佳，最好是5 0 %以下接近0。又，立體編物的壓縮撓屈時的殘留變形量爲3 0 m m以下的話，長時間或返覆坐後彈性復原少而有助於提高形態保持性。2 0 %以下更佳。最好是1 5 %以上接近 0 ° 爲了減少立體編物的壓縮撓屈時的滯延損耗及殘留變形量，將構成表背纖維在0 %以上的伸長率進行伸長熱處理的方法等，就可以達成。熱處理，可以在原線製造的階段、或假捻、流體噴射加工等的線加工階段以欠給進行熱處理，或也可以在針織物的階段進行伸長熱處理。在針織本紙張尺度適用中國國家標準（CNS ) A4規格（210X：Z97公釐） 565638 A7 _____B7___ 五、發明説明（4 物進行熱處理的情況時，在寛方向5 %以上的伸長率進行熱處理較佳。

Description of the invention () [Industrial fields of use] (Please read the precautions on the back before filling out this page) This invention is about suitable for use in automobiles, railway vehicles, etc. Cushioning materials for seat cushions of aircrafts, baby seats, strollers, furniture, office use, bedding, bedding, mattresses, cushioning materials such as cushions for preventing cushions, cushions such as pillows and sleeping pads, spacers for clothing, etc. Retaining profiles, cushioning materials, thermal insulation materials, upper cushion materials for shoes, middle cushion materials, or three-dimensional knitted fabrics such as supports or protectors. [Previous technology] The three-dimensional knitted fabric composed of the knitted fabrics on the front and back layers and the connecting lines connecting the knitted fabrics on the two layers uses the functions of cushioning, air permeability, heat retention, and body pressure dispersion, etc. Used in various buffer materials. These three-dimensional knitted fabrics are printed by the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The monofilament is used in the connecting line forming the middle layer, and the bending elasticity of the single filament is used to provide cushioning in the thickness direction of the three-dimensional knitted fabric. A method for improving the cushioning property and compression recovery property of three-dimensional knitted fabrics is disclosed in Japanese Patent Application Laid-Open No. 1 1-2 6 9 7 4 7 in which a monofilament with good elastic recovery properties is used for the connection line to make the three-dimensional knitted fabrics more flexible. Three-dimensional knitted fabric with good compression recovery. However, because the shape of the monofilament of the connecting wire is not taken into account, cushioning properties with elasticity cannot be obtained, and when it is used over a long period of time, the elasticity or thickness may be reduced. In addition, since the elongation characteristic and the compression flexion characteristic of the knitted fabric on the front and back of the three-dimensional knitted fabric are not taken into consideration, when a hammock-type seat cushion is made, good cushioning properties cannot be obtained. In addition, Japanese Patent Laid-Open No. 2000-1 8 7 0 7 7 discloses that a three-dimensional knitted fabric is set on a seat cushion frame to be used as a hammock-type seat cushion, but the cushioning property in the case of repeated use is disclosed. The durability does not apply to the Chinese standard (CNS) A4 specification (210 × 297 male thin ") 565638 A7 ____B7 5. Description of the invention (j points. (Please read the precautions on the back before filling this page) The object of the present invention is to solve the aforementioned problems and provide a three-dimensional knitted fabric having cushioning properties including elasticity, which is not easy to damage the elasticity even after repeated use or long-term use, and has excellent cushioning durability. Specific purpose: In particular, when used in a hammock-type seat cushion, it exhibits a cushioning property with a rebound feel, and has a good personal fit, and does not return to its original shape after sitting, that is, it has less elastic recovery. Three-dimensional knitted fabric with excellent shape retention. A further object of the present invention is to provide a three-dimensional knitted fabric with high frequency vibration attenuation. [Disclosure of the Invention] The present invention is directed to a three-dimensional knitted fabric connected by a combination. The diameter and bending shape of the monofilament of the knitted fabric on the front and back of the object, the compression characteristics of the three-dimensional knitted fabric, the compression and flexion characteristics, and the structure of the three-dimensional knitted fabric composed of the fibrous material have been repeatedly studied to obtain the invention. Printed by the Consumer Cooperative of the Property Bureau. In other words, the knitted fabric 5 of the present invention is a three-dimensional knitted fabric composed of a knitted fabric on the front and back layers and a connection line of monofilaments connecting the knitted fabric on the two layers. : The curvature of the monofilament in the three-dimensional knitting is 0. 〇 1 to 1.6, the bending elongation of the monofilament at 50% compression of the three-dimensional knitted fabric is 20% or less. [Example] A three-dimensional knitted fabric for a seat cushion of the present invention will be described with reference to the drawings. Formed by circular knitting machine knitting machine, double circular knitting machine and cross knitting machine. The paper size is applicable to China National Standard (CNS) A4 specification (210 X 297 mm). B7 V. Description of the invention (3) In the case of knitting, the connecting line connecting the knitted fabric on the front and back must be knitted in a state bent in a certain direction. Therefore, if a force in the thickness direction is added to the three-dimensional knitted fabric, the bent connecting line will be more bent, but if the force is released, the connecting line will return to its original state. At this time, the bending and recovery of the connecting line greatly affects the cushioning property of the three-dimensional knitted fabric. The present invention is based on this knowledge. In the three-dimensional knitted fabric of the present invention, it is necessary to use a monofilament in at least a part of the connecting line connecting the two-layer knitted fabric on the front and back surfaces, and the curvature of the monofilament positioned between the knitted fabric on the front and back surfaces of the three-dimensional knitted fabric becomes 0 · 0 1 ~ 1 · 6 places are assembled into body fabrics and processed afterwards. here. The so-called curvature of the monofilament is the curvature of an arc formed by the centerline of the monofilament in the portion where the monofilament is most bent in the three-dimensional knitted fabric. FIG. 1 shows an example of the centerline 5 of the monofilament as viewed from the cut surface along the vertical line of the three-dimensional knitted fabric 1. As shown in FIG. The curvature of the monofilament is preferably 0 · 03 to 1 · 0, but more preferably 0 · 05 to 0 · 7. The curvature of the monofilament is less than 0. 〇1, if a load is applied to the thickness direction of the three-dimensional knitted fabric 1, the knitted fabric on the front surface and the knitted fabric on the back surface will be shifted toward the longitudinal direction of the three-dimensional knitted fabric (in the direction of the vertical column), and shearing may occur easily. Deformation and cushioning properties without elasticity due to large hysteresis loss during recovery. Moreover, this tendency will be further increased by repeated compression. When the curvature r i of the monofilament exceeds 1 · 6, it is difficult to cause shear deformation, but it also has cushioning properties without elasticity. The three-dimensional knitted fabric of the present invention preferably has a bending elongation of a monofilament of 50% or less when the three-dimensional knitted fabric is compressed by 50%. Less than 15% is more preferred, and less than 10% is most preferred. Here, the so-called bending elongation of the monofilament is the Chinese national standard (CNS) A4 specification (210X 297 mm 1 " (Please read the precautions on the back before filling this page) at the paper size} 565638 Ministry of Economy Printed by the Consumer Property Cooperative of the Intellectual Property Bureau A7 B7 V. Description of the invention (4) The elongation of the convex side surface of the monofilament where the monofilament has the largest bend under the condition of 50% compression of the three-dimensional knitted fabric. 1 is a cross-sectional view along a longitudinal line of the knitted fabric in a 50% compressed state, but shows an example of a convex side surface 6 where the monofilament has the largest bend. If the monofilament has a bending elongation exceeding 20%, After becoming a compressed three-dimensional knitted fabric, the residual deformation is large, and the three-dimensional knitted fabric with poor compression recovery is not able to maintain the elastic cushioning property after being returned or compressed for a long time. The bending elongation of the monofilament of the three-dimensional knitted fabric, 75% compression When it is 20% or less, 'the compression recovery and cushioning durability can be improved, and the curvature of the monofilament of the three-dimensional knitted fabric and the bending elongation of the monofilament at 50% compression are appropriately set as described above. Fan Within the range, it is necessary to optimize: the diameter of the monofilament as the three-dimensional knitted fabric 1, the weaving structure of the monofilament in the three-dimensional knitted fabric (the swing width in the width direction when the front and back knitted fabrics are connected), and the supply amount of the monofilament when knitted. 3, the post-processing direction of the three-dimensional knitted fabric (amplification rate, overfeed rate), and the monofilament after the post-processing processing into an appropriate shape. Among them, the relationship between the knitted structure of the monofilament and the thickness of the three-dimensional knitted fabric, by The connecting line connects the knitted fabric on the front and the back diagonally to the wide direction of the knitted fabric, and is post-processed with an appropriate expansion ratio. As shown in FIG. 3, the cross-sectional view along the horizontal row makes the The relationship between the thickness TQ (mm) of the three-dimensional knitted fabric 1 minus the thickness of the ground on the front and back sides Η 1 (mm) and the 50% compression of the connection line Η 2 (mm) shown in Figure 4 The reason why it is H1 / H2-0 · 55 is because it is better to make the flexural elongation at 50% compression of the three-dimensional knitted fabric 1 20%. This (Please read the precautions on the back before filling this page ) This paper size applies to China National Standard (CNS) A4 specification (210X2 97 mm) 565638 A7 B7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. When the description of the invention (5), the connecting lines are long Η 1 and Η 2. As shown in Figures 3 and 4, the three-dimensional knitting 1 When viewed from the horizontal cut surface, it is the length on the outer surface of the connecting line 4 between the front knitted fabric 2 and the back knitted fabric 3, and is obtained by photographing and measuring along the horizontal cut surface. Length. When the connecting line is inclined in the horizontal direction, the inclined direction opposite to the inclined connecting line also inclines the connecting line, and it is preferable to make the connecting line into a structure or a cross structure described later. The curvature of the three-dimensional knitted fabric 0 · 0 1 ~ 1. 6,50% Compression bending elongation rate is less than 20% of the ratio of the connection lines of the monofilament, must be 20% of the total number of monofilaments connected to the front and back knitted fabric per unit area of the three-dimensional knitted fabric. % Or more, preferably 40% or more, and more preferably 60% or more. It is better if the connecting threads of the three-dimensional knitted fabric are all monofilaments, but fibers other than monofilaments may be interlaced as required. For example, interlaced multi-filament and false-twisted yarn can reduce the unpleasant sound produced by the friction between the monofilaments during compression. In order to reduce the hysteresis loss during 50% compression to more than 50%, the bending elongation of the monofilament of the connecting wire is adjusted to be more than 20%: the thickness of the three-dimensional knitted fabric, the diameter of the monofilament, and the Tilt status is important. In addition, it is preferable to use a monofilament having a hysteresis loss at the time of bending recovery of 0 ·· 5 c Ν · cm / y a r η or less on the connection line. 〇. 〇3〇1 ^. (: 111 /: 73]:] 1 or less is better, and 〇. 〇1 c N. It is best that c m / y a r η is close to 0. In addition, the relationship between the diameter D (mm) of the monofilament and the thickness T (mm) of the three-dimensional knitted fabric can be satisfied (please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) Α4 specification ( 210 × 297 mm) 565638 A7 B7 V. Description of the invention (β) The relationship of the following formula is better. T 〇 / D ^ 2 0 Here, the thickness To (mm) of the three-dimensional knitted fabric is a thickness measured at a load of 49 〇 Pa. The three-dimensional knitted fabric of the present invention further improves the feeling of elasticity and instantaneous compression recovery when sitting, and the stress relaxation rate after 40 minutes of compression for 1 minute is preferably less than 40%, and the stress relaxation rate Below 30% is better. If the stress relaxation rate is 40% or less, even if a person sits on the three-dimensional knitted fabric for a certain period of time, it can have good instantaneous recovery. When the three-dimensional knitted fabric of the present invention is used as a hammock-type seat cushion, if the compression deflection amount is 10 m m or more and 80 m m or more, a close-fitting feeling with the human body can be obtained and a better sitting feeling can be obtained. The so-called hammock-type seat cushion means that the three-dimensional knitted fabric is formed in the state of a sail by pulling the periphery or at least two sides of the three-dimensional knitted fabric in a state of tension or relaxation in the frame of the cushion or chair. The seat or backrest of a seat cushion. Also, the so-called "compressive deflection amount" refers to the amount of deflection of a three-dimensional knitted fabric when the periphery of the three-dimensional knitted fabric cut into four corners is fixed to a frame and a load is applied to the surface of the three-dimensional knitted fabric in a right angle direction. Back elongation characteristics. If the amount of flexion is less than 10 mm, the amount of sag when the person sits is too small, and the seat cushion surface of the three-dimensional knitted fabric cannot fit on the human body, which makes the fit more rigid. If the amount of flexion exceeds 80 mm, the fit will be good, but after sitting, it will be easy to recover elastically without returning to its original shape, and the shape retention will be insufficient. The compressive deflection is preferably 15 mm to 70 mm, and more preferably 15 mm to 60 mm.

Description of the invention (7) (Please read the precautions on the back before filling in this page) In order to make the compression and flexure characteristics within the appropriate range, the vertical direction of the three-dimensional knitted fabric (in the direction of the vertical column) ) And lateral (direction along the horizontal direction) elongation characteristics and thickness direction compression characteristics are important, but the three-dimensional knitted fabric of the present invention has a longitudinal and lateral elongation of 3% or more and 50% or less. The reason is that it is possible to obtain a hammock-type seat cushion that has a large amount of depression and can improve the fit to the human body. It is more preferably 5% to 45%. In addition, in order to obtain a strong rebound feeling and less elastic recovery after sitting, And the shape-retaining hammock-type seat cushion, the three-dimensional knitting longitudinal and lateral elongation is 0. Above 5% and below 20% are preferred. Above 1% and below 15% are more preferred. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. However, when the three-dimensional knitted fabric is stretched, the longitudinal and lateral elongation distortions are reduced. In order to reduce the elastic recovery after sitting in a hammock-type seat cushion, it is preferably less than 10%. Below 7% is better, below 5% is best. In order to make the longitudinal and transverse elongation and residual deformation of the three-dimensional knitting within an appropriate range, the front and back knitting structure and post-processing method of the three-dimensional knitting become important. If the weave structure on the front and back is a porous structure such as a mesh, the number of structures (number of rows) constituting 1 mesh is preferably 12 or less. The post-processing method is to achieve a balance of elongation in the 縦 direction and the horizontal direction, and It is better to expand in the horizontal direction and heat set. If the knitting structure on at least one of the front and back is a non-porous flat or uneven structure, all the rows can be used: knitting structure formed by knitting arc, or knitting arc structure and composite tissue inserted into the tissue. In order to obtain a large amount of depression in the hammock-type seat cushion and a good snug cushioning property, if the elongation of the three-dimensional knitted fabric is increased, all the rows are not inserted without forming a knitting arc, but at least all the rows. Half of the paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) * 565638 A7 B7 V. Description of the invention (a) (Please read the notes on the back before filling this page) Employees of the Intellectual Property Bureau of the Ministry of Economic Affairs The knitting organization of the rows printed on the consumer cooperatives to form a knitting arc is better. In addition, in order to show the cushioning characteristics of the rebounding feeling in the hammock-type seat cushion and the good shape retention after repetition or sitting for a long time, if the elongation of the three-dimensional knitted fabric is reduced, the insertion line will be straight. The knitted fabric is preferably inserted in the longitudinal direction and / or lateral direction of at least one of the front and back of the three-dimensional knitted fabric. Because the insertion line is linearly inserted into the longitudinal direction and / or the transverse direction, the longitudinal and / or transverse elongation characteristics of the three-dimensional knitted fabric will not greatly affect the deformation of the knitted fabric on the front and back or the mesh shape. Deformation is determined by the elongation characteristics of the insertion wire itself. That is, because a person sits on, the external force acting almost perpendicularly to the surface of the three-dimensional knitted fabric that is laid out in a hammock, and delays the knitted fabric on the front and back of the three-dimensional knitted fabric, because it is not easy to produce a tissue shape or a mesh shape. Deformation between fibers caused by the deformation, so that the shape retention after reversing or sitting for a long time is good. Here, the knitted fabric in which the insertion thread is linearly inserted into at least one of the front and the back refers to a knitting arc and a knitting loop of a bottom thread knitted by a structure such as a lock knit or a plain weave in the longitudinal direction. Between the settlement arcs, the state is inserted with a traverse width of less than 2 stitches per row, or when the settlement arcs are inserted up and down between the settlement arcs connected to the floor of the three-dimensional knitted fabric in the longitudinal direction. The insertion line is inserted across the entire length of the three-dimensional knitted fabric so that the insertion line is close to a straight line. In the case of the horizontal direction, the knitting arc and the settling arc of the bottom line formed by a knitting organization or a plain weaving organization are used to make the insertion line span the full width of the three-dimensional knitted fabric. Inserted into a nearly linear pattern. At this time, the fiber used for the insertion thread is preferably a fiber with good elastic recovery properties such as polytrimethylene terephthalate fiber or polyester elastomer fiber. If it is a monofilament, it is best to apply the Chinese national standard to this paper size (CNS) A4 specification (210X297 mm) ΓΤΠ ~ 565638 A7 ____B7 V. Description of the invention (9) (Please read the precautions on the back before filling this page) Reduce the elongation recovery caused by the friction resistance between the single fibers Obstruction. In addition, in order to prevent slippage with the bottom thread, the insertion thread is preferably joined to the bottom thread by thermal fusion or resin contact. The insertion method of the insertion thread can be inserted in a longitudinal direction using a knitting structure, and can be inserted in a horizontal direction using a double Russell twill knitting machine equipped with a weft insertion device. The knitted structure of the front and back of the three-dimensional knitted fabric does not need to be the same. Although it can be a different knitted structure and different elongation characteristics, if the elongation of the knitted fabric on the back side is less than that of the knitted fabric on the front side, it can increase the number of people. The elasticity produced by the monofilament when sitting, and the fit to the human body is good. When the insertion thread is inserted linearly in the longitudinal direction and / or the lateral direction, it is also preferable to insert the knitted fabric on the back side of the three-dimensional knitted fabric. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. If the hysteresis loss of the three-dimensional knitted fabric is 65% or less, when it is used as a hammock-type seat cushion, it has a cushioning effect of rebound. Better. 60% or less is more preferable, and 50% or less is preferably close to 0. In addition, when the amount of residual deformation during compression flexion of the three-dimensional knitted fabric is 30 mm or less, the elastic recovery is reduced for a long time or after sitting, which contributes to improvement of form retention. Below 20% is better. It is preferable that it is more than 15% and close to 0 °. In order to reduce the hysteresis loss and residual deformation of the three-dimensional knitted fabric during compression and flexion, a method of elongating heat treatment of the elongation of the surface back fiber above 0% can be achieved. . The heat treatment may be performed by under-feeding at the stage of the original thread manufacturing, or at the thread processing stage such as false twisting, fluid jet processing, or the elongation heat treatment may be performed at the stage of the knitted fabric.

Moreover, the three-dimensional knitted fabric of the present invention has a compression recovery rate of more than 90% at room temperature, and a compression recovery rate of 70% or more under its atmosphere. It is better that the compression recovery rate at room temperature is more than 95%, and the compression recovery rate at 70 ° C atmosphere is more than 75%. If the compression recovery rate is more than 90% at normal temperature, Under normal use, there is less elastic recovery and good cushioning. Moreover, if the compression recovery rate is more than 70% in a 70 ° C atmosphere, it can be maintained even after being used in a severe high temperature environment. Good elasticity and low cushioning. The monofilament used for printing the connection thread of the three-dimensional knitted fabric of the present invention by the Ministry of Economic Affairs, the Intellectual Property Office of the 8th Industrial Cooperative, can be used: polytrimethylene terephthalate fiber, benzene Butyl formate fiber, polyethylene terephthalate fiber, polyamide fiber, polypropylene fiber, polyvinyl chloride fiber, polyester elastomer fiber, etc. If polytrimethylene terephthalate fiber is used in part, it will have cushioning properties with elasticity, and the cushioning properties after repeated or long-term compression will be good.

Description of the invention (1) 1 Moreover, at the elongation of polytrimethylene terephthalate fiber of 0% or more, If elongation heat treatment is performed at the processing or knitted fabric stage, it is preferable because the hysteresis loss and residual deformation amount at the time of flexion can be compressed. In the case of knitted fabrics, elongation heat treatment is performed at an expansion rate of 5% or more. It is better to manufacture the cross-sectional shape, which can also be round, triangular, L-shaped, T-shaped, Y-shaped, W-shaped, octave-shaped, flat-shaped, chuck-shaped, polygonal, multi-lobed, hollow, or Unshaped.

It is preferable to use a bulky thread such as a false twist processing line or a spinning line of a multifilament on at least the side of the three-dimensional knitted fabric. Further, in order to attach strong stretchability or compression flexure and recovery to the three-dimensional knitted fabric, it is preferable to fix the monofilament to the knitted fabric at least on the side of the sheet. However, when the monofilament is a composite yarn such as a juxtaposition, elongation and recovery properties can be further improved. In addition, if the three-dimensional knitted fabric is composed of 100% of polyester-based fibers, the front and back lines and connecting lines can be decomposed and restored to their original state when discarded, and can be reused, and even if burning, harmful gases can be prevented.

Although the coloring method may include: uncolored threads & twisted or cylindrical threads Dyeing method (first dyeing), dyeing method by mixing pigments and dyes into the original solution before spinning (coloring of the original solution), dyeing with three-dimensional knitting & printing method, etc., but dyeing with three-dimensional knitting It is easy to maintain the three-dimensional shape and the processability is poor, so it is better to dye first or the original solution. The fineness of the monofilament used for the connection line can usually be 20 ~ 150 dtex thickness. In order to attach the three-dimensional knitted fabric with elasticity For better cushioning properties, the thickness of the monofilament is preferably 1,000 to 10,000 dtex, and more preferably 2000 to 900 dtex.

It is also not easy to lose elasticity over time, and has good cushioning durability. In particular, when it is used in a hammock-type seat cushion, it exhibits a cushioning property that is rich in elasticity and has a good fit to the human body '. Moreover, even after repetition or sitting for a long time, there is less elastic recovery and good shape retention. Furthermore, the three-dimensional knitted fabric of the present invention has good vibration attenuation at high frequencies, and is suitable as a cushion for a vibration environment, for example, a cushion material for a vehicle-mounted cushion. [Brief Description of Drawings] Fig. 1 is an example of the centerline of the monofilament as viewed from the cut surface along the vertical line of the three-dimensional knitted fabric. Fig. 2 shows an example of the bent state of the monofilament in a state where the three-dimensional knitted fabric is compressed by 50%, as viewed from the cut surface along the vertical line of the three-dimensional knitted fabric.
